2. C 5. A
3. B 6. C
7. D 8. D
9. A. 3 x 10 km
0.006 = 6 x 10^2
A(1n km^2) = (6 x 10^-3km) (5 x 10^-3km)
6 x 5 = 30
10^-3 x 10^-3 = 10^-3 + -3 = 10^-6
30 x 10^-6km = 3 x 10^1 x 10^-6 = 3 x 10^1 +(-6) = 3 x 10^-5
B. 30 m ; It is better to use square meters
A (in m^2) = (3 x 10^-5)(1 x 10^6)
3 x 1 = 3
10^-5 x 10^6 = 10^-5 + 6 = 10^1
3 x 10^1 = 3 x 10 = 30
